To all fwhom 'it may concern.'

Be 1t known that I, CHARLES C. Duroun,

i' residing at Butler, in the county of Butler and State of Pennsylvania, 'citizen of the United States, have invented or discovered certain new and' useful Improvements in Car-Roofs, of which improvement the following is a specication.

My invention relates to car roots, and the object thereof is to provide a construction which may be easily assembled and repaired, and which will have the required iiexibility to resist, without forming leakage cracks, the torsion strains met in such roofs. j

A further object of my invention is to provide a capping for adjacent free edges oi' the root' sheets, which capping, in conjunction with a particular shaping of such sheets, will 'eliectively prevent, under service andl test conditions, the ingress ofv water to the car.

In the accompanying sheets of drawings, which form part ofmy specification, l have illustrated two embodiments of my invention.' Figure l is a transverse sectional view of a portion of a car roof; Fig. 2 a sectional view taken on the line Ill-II, Fig. l, showing also a portion lonly of the roof, but to enlarged scale; F ig. 3'an isometric view' of a roof unit.; and Fig. 4 a view similar to Fig. 2, but showing a modication of the construction illustrated therein.

In the several ligures like numerals areA used to designate like parts.

@ne feature of my invention concerns the 'general construction of car. roofs to the 'end that they may be built up in separate units, the several parts of which may be independ ently assembled and riveted or otherwise secured together, each unit being subsequently attached to the body of the car. To

such end the transverse and longitudinal frame members are, in this embodimentof my invention, connected together to form a plurality of adjaoently-disposed transverse units or roof segments.

Referring rst to Figs. 1, 2 and 3, each unit comprises two carlines l and la and purlins 2 extending between and rivetedto the carlines, which extend continuously from one side of the carto the other and are symmetrical about the longitudinal center line formed, which units may then be secured to 5 and 5a, the carlines being provided with an integral downwardly bent lug 5 for this purpose. As will readily be seen, a suitable space intervenes between adjacent carlines to receive brackets for attaching the roof caps, the preferred construction of which will be presently explained.- A complete roof unit thus formed is .illustrated in Fig. linished root the adjacent carlines of adja cent units are preferably not connected to each other, thus aiording greater exibility of the rootl frame, so that there will be less liability of its being damaged bythewarping and swaging of the car whentraveling. ln case only a portion of the roof is injured rately repaired ou replaced without dismantling the wholelroof structure.v

In Fig. 4. I have illustrated a combination steel and wood rooh'showing the adaptability of mydmprovemehts to roofs of this char` acter. The carlines lilare of the same genw eral shapeand consti I ion as those of the all-steel roof, but the; ,purlins or nailing strips 7 are made of woo-gl attached by means of bolts 8 to a suitablej' pressed channel 9, which in turn is rivetgjed toV the""c`arlines. Weather boards l0 are nliled to the strips and iorm'a support foi" the roof sheets 3a., which may be of light construction than the plates 3 of the all I case of the all-steel i`-7 roof is made up of in( units, which may bej' t, the combination parately removed at any time.

the side plates e of the ear by means "of bolts In the pendent disconnected roof sheets 3 are itted upon the units thus in an accident, the injured unit may be sepasoy i my invention conthis construction it has been found that'vvater under relatively high velocity, when played upon theroof, finds its way beneath the edges of the caps and over the up-fturned ends of the sheets and into the car. To overcome this point of weakness I provide a y double cap for such joints, and form a waterdeecting ridge inthe roof sheets between the downwardly-extending le s of the caps, so that such water as may be orced lbetween the roof sheet and the outer cap will be deflected upwardly againstthe side of the inner cap, rather than over the up-turned end of the roof sheet as in former constructions.

Referring again to the drawings, and particularly to Figs. 1 and 2 the roof sheets 3 have 11p-turned legs 11 adjacent to the carlines, and ledges 12 adapted to bear upon the tops of the carlines as shown. JAlso, these sheets are provided with water-deflecting ridges 13 spaced' a short distance from the carlines and extending parallel'to them. An inner cap 14 extendsover the 'legs 11 and preferably bears upon the sheets 3 between each leg l1 and ridge 13, while the outer cap 15 includes the inner cap and bears upon the sheets 3 on the opposite or outer sides of the ridge. In order to clamp the sheets to the roof I provide a bracket 20, which may be secured to the ytops of the caps by means of rivets 16, and which may extend into the space between adjacent carlines. These brackets are provided with threaded holes to receive bolts 17, which extend through the spacing member 18, there-being a suitable bolt lock 19 provided to prevent the bolts from becoming. loose. The inner cap 14 is in contact with the outer cap 15 only at the brackets 20, thus leaving a space between the sheets for the passage ot' water from one side of the inner cap to the other.v The ends ofthe caps'are bent downwardly at the side of the' car and extend over a strip of flashing 21 secured to rectangular fascia plate 22, which is attached to the siding23 after suchsiding has been secured to the side plates 4,

4The roof cap construction shown in Fig. 4 is, in all essential respects, the same as that shown-in Fig. 2 and described above, the.

only diEerencc being that the caps lll" and 15a are shallower.

Considering each built-up unit of the roof ne a nai-line, it will be observed that the roof sheets lie within the carlines, and thecaps span the space between them, rather than 4 the sheets extending between, and the caps over the carlines.

I claim as my invention:

1. In a car construction, the combination with oppositelydsposed side plates, of a plurality of roof units each comprising roof sheets and supporting members therefor, said nits being attached at their ends to said .side plates and extending transversely of the car, the adjacent units being'unattached to each other in planes transversely of the said plates and separately removable from the car.

2. In a car construction, the combination with a car frame having as a part thereof oppositely-disposed side plates, of a roof comprising a plurality of separately removable units attached at their opposite ends to said side plates, but unattached to each other in planes transversely of the said plates, each unit comprising two carlines with purlins extending between and rigidly secured to them.

' 3. In a car construction, the combination with a car vframe having as a part -thereof oppositely disposed side plates, of a roof comprising a plurality of separately removable units attached at their opposite ends to said side plates, but otherwise unattaehed to each othervin planes transversely of the said plates; each unit comprising two spaced carlines' consisting of Z-bars and U-sliaped purlins having outstanding flanges attached to the substantially horizontal legs of said Z-bars.

4. In a car roof construction the combination of a roof frame, metal sheets covering said frame and having their adjacent edges turned upwardly, inner and outervcaps extending over said sheet edges, the free edges of said outer cap movably bearing upon said roof sheets, and upwardly extending water detiecting ridges on said sheets between said inner and -uter caps.

5. In a car roof construction, the combination with a carline, and purlins extending from each side thereof, of roof sheets terminating with upturned ends at said carline and provided with upwardly-extending water-deiiecting ridges, ,an inner cap extending over said upturned sheet ends and bearing upon said sheetsv between their upturned ends and said ridges, an outer cap inclcsing said innercap and bearing upon said' sheets beyondfsaid ridges, and means for attaching said' caps to said carline. 6. In a car roof construction, the combination with a camine, and purlins extending "from each side thereof, of roof sheets terminating with upturned ends at said carlineand provided'\.,with upwardly-extendingv water-defiecting ridges, outer ad inner caps extending over the upturned ends of said sheets, the free edges o1 said outer caps bear- In testimony whereof I have hereunto set 111g upon said sheets and inclosing said ridge, my hand. and the free edges of said inner cap being between syaid ridge and said upturned sheet CHARLES C' DUFOUR' 5 ends, and passageways between the tops of Witnesses:
